  • Data set overlay protection
    Patent number: 11614868
    Abstract: A method for preventing data overlays in a data storage system is disclosed. In one embodiment, such a method detects a write operation directed to a storage area of a data storage system. The write operation includes one or more of a format write operation and a full-track write operation. Upon detecting the write operation, the method determines a data set that is associated with the storage area. The method analyzes metadata associated with the data set to determine whether the storage area contains valid data. In the event the storage area contains valid data, the method performs a data protection operation that prevents execution of the write operation and/or logs details of the write operation. A corresponding system and computer program product are also disclosed.
